Here's a pendant I made with silver art clay. I used molding compound to create the 2-part mold from a real pair of acorns. Then used clay and slip. I also included a garnet bead inside each bead that rattles around inside, if you shake them. Mostly to see if I could. I used cork clay as well.
The acorns are vented with a small opening in the top
It's great to make mistakes and get messy! I enjoy cooking, beading, crafting,.. you get the picture!
I have three great girls, and have been married for twenty-three years.
